<dt>In addition to the abbreviations listed below, there will usually be
    an additional number directly after the browser code notation that
    indicates the <a href="../history/browsers.htm">specific version number</a> when
    support for the feature began (eg: <b><i class="fs">N4B2</i></b>
    = Netscape 4.0, Beta 2.) If no version number is present, the browser does not
    support the feature.

<dt><big><b class="mainheading">Formatting Schemes</b></big>
<dt>Differentiation of feature support consists of four levels: first support,
    support (support exists, but the browser/standard was not the first
    to support it), support range (browser supported at one time but no longer
    does) and no support at all. If a particular feature is not supported
    in a browser or standard, the notations will not list the browser/standard.
    I have tried to make the difference between the support levels clear and
    obvious - even to users of older browsers, but some explanation is necessary.
    Simple font styles are used to differentiate between first support (italic, bold),
    support (bold), and support range (underline) while additional colors are
    attached for these settings via style sheets for browsers that support this
    feature. Color coded differentiation is much more visually obvious to a
    reader than plain font styles, but the colors should not be necessary in
    order to read this information properly. The colors I mention below are the
    default style sheet colors I have chosen for the site. If you are using a
    downloaded version of the site, these colors are
    <a href="../ss/changecss.htm">customizable</a>.
